Question

Graph the equation by plotting three points. If all three are correct, the line will appear. 2y=5x+11. I see alot of people ask this, and the answers are always bad! You can't have decimal places in your answer. You have to plot EXACT numbers ie; 5,2 or -5,2. No decimal places.

Answer 1

To find the points, we can choose any value for x, solve for y, and then plot the resulting point. Let's choose x=-2, x=0, and x=3.

When x=-2, we have:

2y=5(-2)+11

2y=-9

y=-9/2

So the first point is (-2,-9/2).

When x=0, we have:

2y=5(0)+11

2y=11

y=11/2

So the second point is (0,11/2).

When x=3, we have:

2y=5(3)+11

2y=26

y=13

So the third point is (3,13).

Now we can plot these three points on the graph. Here's what it looks like:
